Try Aircraft Spruce. I ordered on 1/27 and received a pair today.

Are these the 861-188 floats? Seem to be the -184 floats.

I bought a set of the 861-188's from Lockwood last week.

Lockwood, Leading Edge Airfoil, and California Power all have them on back order. (The -188 which is the latest. )

Will try Aircraft Spruce by phone tomorrow. Web site did not have 188s

Have not been able to locate any replacements. All Rotax dealers tell me they are back ordered currently 30 days or indefinitely.

I only have 74 hours on the carbs.

Now that sucks.

Type and brand and octane of fuel you run? 100LL or MOGAS? What brand of fuel?

The ones I got are the 861-184 which explains their lower price.

Sunoco 93 for the last 40 hours. 100 LL 50/50 for the first 30 hours

I'm frankly tired of replacing my floats - my 4th set just went bad (almost 600 hrs on the engine). I'm certainly not impressed with the quality of the Bing floats, or rather, I'm highly negatively impressed.

I'm actually experimenting with the MS floats. I measured the pin depth of known good Bing floats and the MS floats and found that the MS pin depth was approx. 1/32" lower than the Bing floats which means a slightly higher fuel level in the bowl - I wasn't sure how that would affect engine running. I've just recently started test flying the MS floats. I've been approaching it carefully and only have about 10 hrs on the MS floats. Various power settings from low RPM to WOT, altitudes, attitudes, multiple take-offs, etc. So far I don't see any difference between the MS floats and the Bings. Power, temperatures, etc. all seem perfectly normal so far.

Great update Tom, thanks!! I have no confidence that Bing will ever fix our problem, so a permanent fix would be great. Please keep us updated on your testing. Paul

I just looked at MS website... Is $125 for single float or pair of floats (I hope, I hope)?

What brand and type of fuel are you running in your RV-12 with 4 bad sets of floats?
